Paper Number: SPE-8073-PA
Published: 01 December 1985
... reservoir and borehole fluids can be predicted from the mathematical similarity of poro- and thermoelasticity. A tension-failure condition applies for the prediction of hydraulic fracture initiation in a formation around injection wells. The resulting equations are partially well-known. Similarly...

...James C. Frauenthal; Roland B. di Franco; Brian F. Towler A generalization of upstream weighting is proposed as a method for reducing grid-orientation effects in reservoir simulation. For the two sample problems studied, a piston-flow waterflood and a realistic gas injection, the grid-orientation...

...T. K. Perkins; J. A. Gonzalez Pressure and temperature gradients are created around wellbores during waterflooding or when fluids are injected in connection with any other secondary or tertiary recovery process. These gradients result in changes in earth stresses, which in turn cause hydraulic...
